tion of'apparatus for printing and drying wall paper wherein I haveldevised novel means for taking a roll of blank paper and passing thesame through the ground machine, wherein the firstcolor is applied, thesheet thereafter passing over suitable feeding and drying devices andthen through the printing machine, after which the roll of paper isconducted over additional guiding and drying devices and subjected tofurther treatment. lhen'in the finished condition,- .it is wound uponthe roll ready for shipment, the operating being performed automaticallyand requiring less labor and attendance than heretofore. i

Airadditional feature of my invention consists in the specialarrangement of devices whereby the material is more'eiiiciently dried,and larger quantities of material are acted upon in a given length ofspace and less help is required to operate the same.

For the purpose of illustrating my invention, l have shownonc form ofapparatus which l have found in practice to produce effective andreliable results, although it is to be understood that the variousinstruinentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limitedto theprecise arrangement and organization of these instrumentalities asherein shown.

Figure 1 represents a vertical sectional and diagrammatical view of theright hand portion of an apparatus for printing, treating and dryingwall paper, embodying one form of `my invention. Fig. 1JL represents asimilar view of the left hand portion. of the apparatus. Fig. '2represents-on an enlarged scale, a sectional view ofa-structure similarto that shown in the lowerportion of Fig. 1a. Fig. 3 represents `on anenlarged scale, a section on line w-a, Fig. 1a. Fig. e

represents a side elevation of the power transmission means in the righthand end ot the apparatus. .L F ig. 4.a represents the Aleft hand end ofthe apparatus and is compleiuentaryy to .F ig. 4.

Similar vnumerals of reference indicate corresponding parts in thefigures.

Referring tothe drawings. In describing my invention, I will begin withth: blank and trace the roll of paper from the blank to the nishedproduct during the -successive treatments to which it is subjected.

Referring first to Fig. 1, which as stated represents the right handportion of my machine, 1 designates a roll of blank paper, which ismounted in any suitable supports or framework as 2. In practice theblankroll or reel 1 is usuallyV about three hundred pieces, each piece beingeight yards in length, the roll or reel being placed in position as itcomes from the paper mill. The paper 3 from the roll 1 passes over thefeed roller et, which it will be understood is driven by any suitablemeans, the blank sheet 3 being fed between the feed roller Il and theiron holder 5 located directly above it, substantially as seen in thelower portion of Fig. 1. The sheet 3 next passes under the strip 6 ofcanvas or other material depending freely from its support 7, in orderto make festoon 8. The paper from the roll travels at aI rate-of speedin excess of the rate of an endless belt or apron 9, which passes aroundrollers 10 and 1l, of which the. roller 1() is preferably driven whilethe roller 1 1'revolves in its bearings. Any slack of the apron is takenup by the roller 12. It will be seen that the paper passing out frombeneath the sheet or curtain (l at a rate of speed in excess of theapron 9 tends to curl or turn up into shapes of the character indicatedvin the lower portion of Fig. 1, the curtain or sheet 6 being raised atintervals by the paper to permit vthe curved wave of the lfestoon topass thereunder, dropping immediately to exert a retarding lor draggingeffect upon the sheet in order to form the nextl festoon. This is morefully set out 4in connection with Fig. 5.

The festoons 8 supply paper for the ground machine -13 as indicated atthe point 14, this machine being timed to take the paper at the samespeed as that of feed roller il. AIn the ground machine the tirs-t coloris placed on the paper, the blank 14. leading or emerging from theground machine as indicated at 15 and the blank4 with thetii'st colorthereon, as indicated at 16, now passes over the endless apron 17 whichtravels over the rollers 18 and 19, the roller 18 being shown in Fig. 1and its coacting roller 19 being shown in Fig. 1.

The paper 16 after passing over the apron '.Fig. 1a and pass over theapron 31 which travels 'on the rollers32 as seenin Fig. 1? and. theroller 33 seen in Fig. 1, said apron l31 being supported in its travelby the rollers 34 and 35 which are arranged in pairs, as indicated inFig. 1. to the right of the roller 33, the strip 30 passes over therollers or tension devices 36, 37, 38, 39 and 40, as indicated in Fig.1, passing thence into the printing machine as indicated at 41,- inwhich latter the printing is eii'ected,it being apparent from theforegoing that the paper has received its first color in the groundmachine and has been sutciently dried and thereafter having received thedesired impression -from the printing machine 41. It 'will be apparent-that it only remains to properly dry and reel the paper for shipment,which operation l will now be described. The stri of paper afterleaving-the printing machine '41 will now be indicated as 42 and passesover the apron 43, which travels over the rollers 44 and 45, theintermediate portion of the ,1

apron being supported by the pairs of rollers 46 and 47, as indicated inFig. 1. After passing to the left of the roller 45, the strip 42 travelsover the apron 48, which isy supported on the rollers 49 and 50, thencepassing downwardly as indicated in Fig. 1tl upon the apron 51 which issupported upon the'rollers 52 and 53. passing down and under the roller53 passes over the feed 'roller 54 upon which is an over the'rollers 59,seen in Fig. 1 and the roller 60 seen in Fig. 1, thefestoons 57 nowdisappearing into strip form again, as seen at the left of Fig. 1, andto which l have applied reference and passing under a tension device 61and thence over the rollers 62 and 63 and under the strip 64 of canvasor similar material, whereby the' festoons 65 are formed.

66 designates the. apron.supporting the .t'estoons ,65, said apronpassing over the After passing The strip 42 after I rollers 67 -and' 68and. being kept taut by the roller 69. The festoons 65 after leavingthel apron 66, passas indicated at 74 over the slide 71 and thence on tothe reel 72, upon which the paper in itsfinished condition is wound inpractice the length of sixteen yards. YIt will be understood that inpractice the rollers 49, 53 and 54 are caused to rotate in unison andserve to cause the proper moveinent of' their respective aprons and the.paper traveling thereover. In practice l employ suitable beltiiig orpower transmission devices common to the rollers'49, 53 and 54,'so thatthe same are caused .to rota-te in unison in the proper direction. ltwill also be understood that the rollers 18, and 23 are actuated .inunison in the proper directions by suitable power transmission devices.It will also be understood that the 'rollers 52 and 62 seen in Fig. 1tLare connected by proper belting or power transmission devices, so as tocause the saine to be driven in unison.

It will be understood that the proper drying of the sheet o1" strip ofpaper during its l travel over the various aprons is, yeffected by meansof the piping 73, which may be used for steam or ho`t air. omitted -toshow the source of supply of steam or hot air, as it will be understoodthat the heating medium may be taken from any suitable source and thevarious series of heating pipes can be coupled up in any suitablemanner, as will be evident to those skilled in this art. The structureby which .l these various relations and movements of the aprons aremaintained is set out in Figs. 4

and 4a.

It will be understood that in practice the g reel 72 revolves at a veryhigh speed and that the saine receives its power as indicated in. theseFigs. 4 and 4a, various shafts, belting, pulleys and speed devices beingindicated therein. Starting witli the main shaft 4.75, the power istransmitted through the main belts 76, 77A and 78 with a constantlyincreasing speed to the final pulley connected to the reel 72. Thelground machine and f printing machine are driven by a system of ironroller and thence under a strip 56 of canvas or lother suitablematerial, wheref by the. festoons 57 are formed, which are supported bythe apron 58 which passes belting, the printing machine beingdriven fromthe main shaft 7 5, by means of belt 79, cone pulleys 80 and S1 andshaft 82.

shown in Fig. 4, by belts S7, 92l and 93. Special provision has to bemade for driving the various aprons which support the festooiis of wallpaper in the drying rooin and before entering the ground machine and lafter leaving the drying rooin, in order that j the tight side or faceof said aprons will be I have purposely The ground machine is driven, asclearly l on top thus giving a straight and smooth j surface forsupporting said f'estoons. The i apron 53 in the drying room is drivenfrom I the main shaft through belts 84, chain geart again, the aboveoperation being repeated4 elige? ing, and belt 86, as is clearly seen byret ereiice tothe figures. Apron 27 in the dryrooinis driven by ymeansof beits 87, Sti,

Si), chain gearing 90, belt 91 and shaft 29jsuchlength of wall paper isexposed to the drying atmosphere of the drying room.

Referring to Fig. 2 vdetails of a festoon former are shown, whichoperates substantially as follows :"-The wall paper after passing overthe feed roll 52 passes down the space between the inner surface of thedep iding strip 56 of canvas or 'similar inaterial. and the surfacespeedof the feedroll 54 is considerably in excess of the surface speedof the apron 58 and consequently the -will paper after coming in contactwith said apron is forced upv andfoutwardlyaway from said feed wallpandcontinues horizontally with the movement -of said apron until saidcanvas strip passes over the upper'surrace ot the festoon,and falls backinto place and a continuing series of festoons" formed. The otherfestoons are made in like'manner.
